Gyokuro is a type of Japanese green tea that is grown in the shade rather than in full sun. The name “gyokuro” translates as “jewel dew” or “jade dew”. Gyokuro is considered one of the finest Japanese teas.
Gyokuro plants are shaded from the sun for several weeks while the young leaves develop in the spring. This slows the growth, allowing the tea leaves more time to develop flavor and depth. Gyokuro has less catechin (tea tannin) than other teas, resulting in a smooth, oceanic cup. It has a hearty-sweet umami flavor, a dew-like aroma, and less astringency.
Gyokuro is very high in caffeine, with 120-140 milligrams of caffeine per cup, which is more caffeine than a small cup of coffee. The long shading process contributes to the high caffeine content.
Gyokuro is often made from specialized varieties such as Asahi, Okumidori, Yamakai, and Saemidori. The limited quantity and harvest period, along with the extra labor that goes into cultivating, contribute to the price of Gyokuro.
